The large cell neuroendocrine carcinoma is uncommon and its diagnostic criteria was recently established as pulmonary neuroendocrine carcinoma. A 74-year-old man who was a heavy smoker without symptoms was presented with a lung mass in right lower lobe. He was diagnosed as having large cell neuroendocrine carcinoma by needle biopsy. He was treated with right lower lobe lobectomy and mediastinal lymph node dissection. We experienced one case of large cell neuroendocrine carcinoma of lung and report it with reference.

Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psam-momatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors in the anterior mediastinum without complications.

지방모세포종은 태생기 지방조직에서 기원하는 드문 양성종양으로 대부분 소아기에 발생하는데 이 종양의 약 70%는 사지에서 나타나고 간혹 다른 부위에서 보고되기도 한다. 저자들은 좌측 후종격동과 좌측 쇄골상부에 양성 지방모세포종을 보인 3세된 남아를 치험한바 있다. CT 소견상 지방을 함유한 종괴가 정상적인 흉강내 구조물을 누르고 있었고, 쇄골상부 및 종격동으로부터 합병증없이 절제되었다. 종괴는 황색을 띠었으며, 병리조직검사상 지방모세포종으로 진단되었다.

The coincidental occurrence of squamous cell carcinoma and leiomyoma in the esophagus is rare. A 56 year-old male referred to chest surgery department to evaluate the mediastinal mass which had found on a health examination. The diagnosis was confirmed esophagoscopy and surgery. We report a case of synchronous squamous cell carcinoma and leiomyoma in esophagus and reviewed references to the literature.

This research represents an attempt to study the postoperative results among 32 patients who underwent complete resections of primary lung and involved mediastinal lymph nodes between January 1988 and June 1993. Ages ranged from 34 to 73 years with a mean age of 51.31 $\pm$ 8.17 years. There were 29 male patients[90.6%]. Left lung cancers were more frequent than right lung cancers. There were 19 cases of left lung cancers accounting for 59.4% of the total lung cancers. The difference, however, was insignificant. There was no T1 lesion. T2 and T3 lesions were 21[65.6%] and 11 cases[34.4%], respectively. As for cell type, squamous cell carcinomas were reported in 25 cases making up 78.1% of the cell types. Pneumonectomy was conducted on 20[62.5%] cases. Lobectomy and sleeve lobectomy were conducted on 12[37.5%] cases respectively. Mediastinal lymph node involvemednts were most frequent in subcarinal lymph node[9/13] among right lung cancers, while subaortic lymph noce[12/19] was most frequent among left lung cancers. Postoperative complications were reported in 18.9% of the total cases, including 2 cases each of paralysis of the recurrent laryngeal nerve and 1 case each of chylothorax and pyothorax. They were more frequent among patients who underwent pneumonectomy. The operative mortality stood at 3.1% with 1 patient who underwent pneumonectomy dying of pulmonary edema. The 1-year and 5-year survival rates were 50.8% and 30.1%, respectively. Patients treated with squamous cell carcinoma, involvement of single level mediastinal lymph node and lobectomy showed a higher level of survival. These fidings suggest that a long-term survival can be expected of a considerable number of N2 non-small cell lung cancer patients with a selective complete surgical resection of primary lung cancers involved mediastinal lymph nodes.

For the purpose of clinical analysis In mediastinal tumors, 51 patients with mediastinal tumor who were surgically treated from February 1984 to February 1994 in Chunan hospital of Soonchunhyang university were reviewed. There were 21 male and 30 female patients in the study. Age ranges from 11 months to 75 years, with the mean 39.4$\pm$ 18.8 years. Symptoms and signs were asymptom(21.6%), chest d scomfort(19.6%), dyspnea(15.7%), ptosls(15.7%), general weakness(13.7%) and chest pain(9.8%). The most frequent tumor location was anterosuperior mediastinum(60.8%) followed by posterior(25.5%) and middle(13.7%) mediastinum. In the pathological viewpoint, thymoma(33.3%) was the most frequent type followed by neurogenic tumor(25.5%) an'd germ cell tumor(19.6%). All of benign tumors(46 cases) were completely removed and malignant tumors(5 cases) were treated with rAdiotherapy after operation. The postoperative complications were 2 wound dehesences, 1 pneumothorax, 1 vocal cord palsy and 1 prolonged mechanical ventilation.

Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease(RDD) is a rare type of histiocytosis syndrome, that presents in its most typical form as massive, painless, bilateral lymph node enlargement in the neck during the first or second decade of life. The disease involves extranodal site in over 25% to 43% of the cases, however cases of extranodal RDD without nodal disease have rarely been reported. The involved sites of extranodal RDD have been reported various that were orbit, ocular adnexae, head and neck, upper respiratory tract, breast, gastrointestinal tract, CNS, etc. A 35 year-old man was present with pleural pain on left anterior chest and anterior mediastinal mass, that underwent an excision to remove the suspected invasive thymoma, and the diagnosis was confirmed to extranodal Rosai-Dorfman disease.

The recurrence of an anterior mediastinal mass was discovered incidentally on the chest film for an asymptomatic 72-year-old female. She underwent the mass resection at the same site in 1989 and was diagnosed as a paraganglioma of the anterior mediastinum. She had poorly controlled hypertension which was converted into normal blood pressure after the first operation. During the follow up, the catecholamine levels were within normal limits, and there were no evidence of recurrence of the tumor. However, 6.3 years later, the mass recurred at the same anterior mediastinum. The patient had no hypertension and catecholamine levels were still within normal limits. The recurring mass was successfully removed and had the same histological findings - recurring paraganglioma.

A 35-year-old man was admitted to Korea University Anam Hospital for evaluation of intermittent chest pain. Computed tomography of the chest showed enlargement of a previously identified anterior mediastinal mass and also a well-defined, circumscribed mass in the subcarinal area, surrounded by the roof of the left atrium, right pulmonary artery, and the carina. Complete resection of the intrapericardial tumor was performed through median sternotomy without cardiopulmonary bypass. Pathologic examination identified the tumor as schwannoma, of an ancient type, diffusely positive for the S-100 antigen. Unlike other reported cases, grossly, the tumor did not seem to be involved with any nerve.

This report is an analysis of 43 cases of primary mediastinal tumors and cysts which were treated in the Department of Thoracic and Cardiovascular Surgery, Tae Jeon Eul li General Hospital from January, 1986 to April, 1995. There were 19 males and 24 females, and their ages ranged from 4 years to 68 years, with mean age of 31.3 years. The most common symptoms were dyspnea 48.8%, chest disconyort 39.5%, cough )4.9%, and chest pain 23.3%, and the most frequently encountered location of tumor was anterior mediastinum followed by posterior, and middle mediastinum. From the pathologic viewpoint, teratoma was the most frequent type followed by neurogenic tumors, cysts, thymoma, and Iymphoma. The most useful diagnostic method was plain X-ray examination of the chest, and final diagnosis could usually be made only after an operation. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation There were 7 (16.3 %) cases of postoperative complications, and there was no postoperative mortality.
